DETAILED DESCRIPTION

[1. Mode of Detachably Attaching Game Machine to Vehicle]

A mode in which a game machine 100 is detachably attached to a vehicle 1 will be described with reference to FIGS. 1 to 3. The vehicle 1 corresponds to a mobile body of the present disclosure, and the game machine 100 corresponds to a terminal device of the present disclosure. Referring to FIG. 1, the game machine 100 includes a game machine body 110, and a left controller 170 a and a right controller 170 b for operating the game machine body 110. The left controller 170 a and the right controller 170 b correspond to an operation terminal of the present disclosure. The game machine body 110 includes a display 141 and a speaker 142.

The left controller 170 a is detachably held on the left side surface of the game machine body 110 by a holding unit (not illustrated in the drawings) provided on the left side surface of the game machine body 110. In addition, the right controller 170 b is detachably held on the right side surface of the game machine body 110 by a holding unit (not illustrated in the drawings) provided on the right side surface of the game machine body 110.

When the left controller 170 a is attached to the game machine body 110, a connector 185 a is connected to a left connector 152 a of the game machine body 110, thereby enabling wired communication between the left controller 170 a and the game machine body 110. Similarly, when the right controller 170 b is attached to the game machine body 110, a connector 185 b is connected to a right connector 152 b of the game machine body 110, thereby enabling wired communication between the right controller 170 b and the game machine body 110. As a specification of wired communication, for example, a Universal Serial Bus (USB) (registered trademark) is adopted.

Graphic A1 of FIG. 1 illustrates a state in which the left controller 170 a and the right controller 170 b are attached to the game machine body 110. In this state, a user of the game machine 100 can play a game by operating a button 174 a and a stick 175 a of the left controller 170 a with a left hand and operating a button 174 b and a stick 175 b of the right controller 170 b with a right hand.

Graphic A2 of FIG. 1 illustrates a state in which the left controller 170 a and the right controller 170 b are removed from the game machine body 110. In this state, the left controller 170 a and the right controller 170 b perform wireless communication with the game machine body 110. Bluetooth (registered trademark) is adopted as a specification of wireless communication, for example. The user can play a game by operating the left controller 170 a or the right controller 170 b from a place away from the game machine body 110.

The vehicle 1 includes a steering wheel 2 operated by a driver, and a display 4 and speakers 5 a and 5 b are provided on a dashboard 3 of the vehicle 1. The steering wheel 2 corresponds to a steering unit of the present disclosure and is rotated and displaced left and right according to an operation by the driver. The steering wheel 2 is provided with an operation terminal holding unit 50 for detachably attaching the right controller 170 b. In addition, the dashboard 3 is provided with a game machine body holding unit 60 for detachably attaching the game machine body 110 to a predetermined place visually recognizable by the driver and another passenger. The game machine body holding unit 60 corresponds to a terminal device holding unit of the present disclosure.

The operation terminal holding unit 50 has a recessed shape corresponding to an outer shape of the right controller 170 b. In FIG. 1, a situation in which the right controller 170 b is attached to the operation terminal holding unit 50 is indicated by arrow R1, and when a passenger such as a driver or the like fits the right controller 170 b into the recess of the operation terminal holding unit 50, the right controller 170 b is held by the operation terminal holding unit 50 and fixed to the steering wheel 2.

At this time, the connector 185 b of the right controller 170 b is connected to a connector 51 of the operation terminal holding unit 50. Since the connector 51 of the operation terminal holding unit 50 is connected to a vehicle electronic control unit (ECU) 10, wired communication between the vehicle ECU 10 and the right controller 170 b becomes possible by attaching the right controller 170 b to the operation terminal holding unit 50.

Note that the operation terminal holding unit 50 may hold the left controller 170 a instead of the right controller 170 b. Alternatively, the operation terminal holding unit 50 may be configured to be able to hold either one of the left controller 170 a and the right controller 170 b. When the left controller 170 a is attached to the operation terminal holding unit 50, the connector 185 a of the left controller 170 a is connected to the connector 51 of the operation terminal holding unit 50, and wired communication between the vehicle ECU 10 and the left controller 170 a becomes possible.

The game machine body holding unit 60 has a recessed shape corresponding to an outer shape of the game machine body 110. In FIG. 1, a situation in which the game machine body 110 is attached to the game machine body holding unit 60 is indicated by arrow R2, and when a passenger such as a driver or the like fits the game machine body 110 into the recess of the game machine body holding unit 60, the game machine body 110 is held and fixed by the game machine body holding unit 60. At this time, a lower connector 151 of the game machine body 110 is connected to a connector 61 of the game machine body holding unit 60. Since the connector 61 of the game machine body holding unit 60 is connected to the vehicle ECU 10, wired communication between the vehicle ECU 10 and the game machine body 110 becomes possible by attaching the game machine body 110 to the game machine body holding unit 60.

FIG. 2 illustrates a state in which the right controller 170 b is attached to the operation terminal holding unit 50. In this state, an attitude of the right controller 170 b changes according to an operation of the steering wheel 2 by the driver. In this state, the driver of the vehicle 1 can operate the right controller 170 b to give an instruction to the game machine body 110 and the vehicle ECU 10, and the passenger other than the driver can operate the left controller 170 a to give an instruction to the game machine body 110 and the vehicle ECU 10. In addition, the passenger can watch an image displayed on the display 141 of the game machine body 110 and listen to sound output from the speaker 142.

Note that the left controller 170 a and the right controller 170 b can perform wireless communication with the game machine body 110 even in a state of being attached to the operation terminal holding unit 50. In addition, the left controller 170 a, the right controller 170 b, and the game machine body 110 may be configured to be able to perform wireless communication with the vehicle ECU 10.

Next, FIG. 3 illustrates another configuration in which an operation terminal holding unit 50 a to which the left controller 170 a is attached and an operation terminal holding unit 50 b to which the right controller 170 b is attached are provided in the steering wheel 2 as the operation terminal holding units. Configurations of the operation terminal holding unit 50 a and the operation terminal holding unit 50 b are similar to the operation terminal holding unit 50 illustrated in FIGS. 1 and 2.

When the left controller 170 a is attached to the operation terminal holding unit 50 a, the connector 185 a (see FIG. 1) of the left controller 170 a is connected to a connector 51 a of the operation terminal holding unit 50 a, and wired communication between the left controller 170 a, the game machine body 110, and the vehicle ECU 10 becomes possible. Similarly, when the right controller 170 b is attached to the operation terminal holding unit 50 b, the connector 185 b (see FIG. 1) of the right controller 170 b is connected to a connector 51 b of the operation terminal holding unit 50 b, and wired communication between the right controller 170 b, the game machine body 110, and the vehicle ECU 10 becomes possible.

In the configuration of FIG. 3, attitudes of the left controller 170 a and the right controller 170 b change according to an operation of the steering wheel 2 by the driver. The game machine body 110 and the vehicle ECU 10 can recognize the attitude change of the left controller 170 a by communication with the left controller 170 a and can recognize the attitude change of the right controller 170 b by communication with the right controller 170 b.

[2. Configuration of Game Machine Body]

A configuration of the game machine body 110 will be described with reference to FIG. 4. The game machine body 110 includes a terminal device processor 120, and a memory 130, a communication unit 140, a display 141, a speaker 142, a microphone 143, an acceleration sensor 144, and an angular velocity sensor 145 connected to the terminal device processor 120. Further, the game machine body 110 includes a card slot 150, a lower connector 151, a left connector 152 a, and a right connector 152 b connected to the terminal device processor 120. The terminal device processor 120 corresponds to a computer. The memory 130 corresponds to a recording medium.

The display 141 is a touch panel in which a touch sensor is disposed on a surface of a flat-type display device such as a liquid crystal display (LCD) or the like, displays a screen according to an image control signal output from the terminal device processor 120, and inputs an operation signal according to a touch operation by a user to the terminal device processor 120.

The speaker 142 outputs a sound (voice, attention sound, music, and the like) corresponding to an acoustic signal output from the terminal device processor 120. The microphone 143 detects a sound such as a user's vocalization and the like and inputs a sound detection signal to the terminal device processor 120. The acceleration sensor 144 detects acceleration of the game machine body 110 and inputs an acceleration detection signal to the terminal device processor 120. The angular velocity sensor 145 detects an angular velocity of the game machine body 110 and inputs an angular velocity detection signal to the terminal device processor 120.

The memory 130 stores a control program 131 for controlling an overall operation of the game machine body 110, an interaction providing program 132 for executing interaction control to be described later, and a game application program 133 for executing a game. The card slot 150 reads and writes data from and in an inserted memory card 155.

As described above, the right connector 152 b is connected to the right controller 170 b, or is connected to the connector 51 of the operation terminal holding unit 50 or the connector 51 b of the operation terminal holding unit 50 b.

The interaction providing program 132 may be read by the terminal device processor 120 from an external recording medium such as the memory card 155 or the like and stored in the memory 130, or may be downloaded from the support server 510 by the communication unit 140 and stored in the memory 130. The external recording medium may be a magnetic disk, an optical disk, or the like in addition to a flash memory such as the memory card 155 or the like. The memory 130 and the external recording medium are non-transitory tangible recording media that can be read and written by a computer.

The terminal device processor 120 reads and executes the control program 131 to control the overall operation of the game machine body 110 and reads and executes the game application program 133 to execute the processing of the game. In addition, the terminal device processor 120 functions as an operation terminal holding recognition unit 121, a terminal device holding recognition unit 122, an interaction control unit 123, and a content information output unit 124 by reading and executing the interaction providing program 132.

When recognizing that wired communication is established between the left controller 170 a and the vehicle ECU 10 by communication with the vehicle ECU 10, the operation terminal holding recognition unit 121 recognizes that the left controller 170 a is held in the operation terminal holding unit 50 (configurations of FIGS. 1 and 2) or the operation terminal holding unit 50 a (case of FIG. 3). Similarly, when recognizing that wired communication is established between the right controller 170 b and the vehicle ECU 10 by communication with the vehicle ECU 10, the operation terminal holding recognition unit 121 recognizes that the right controller 170 b is held in the operation terminal holding unit 50 (configurations of FIGS. 1 and 2) or the operation terminal holding unit 50 b (configuration of FIG. 3).

When recognizing that wired communication is established between the game machine body 110 and the vehicle ECU 10, the terminal device holding recognition unit 122 recognizes that the game machine body 110 is held in the game machine body holding unit 60. The interaction control unit 123 executes interaction control when the operation terminal holding recognition unit 121 recognizes that at least one of the left controller 170 a and the right controller 170 b is connected to the operation terminal holding units 50, 50 a, and 50 b and the terminal device holding recognition unit 122 recognizes that the game machine body 110 is held in the game machine body holding unit 60. Details of the interaction control will be described later.

When the operation terminal holding recognition unit 121 recognizes that at least one of the left controller 170 a and the right controller 170 b is connected to the operation terminal holding units 50, 50 a, and 50 b and the terminal device holding recognition unit 122 recognizes that the game machine body 110 is held in the game machine body holding unit 60, the content information output unit 124 outputs information of predetermined content from the display 141, the speaker 142, and the like of the game machine body 110. The predetermined content is content that can be used by installing a predetermined application in the game machine body 110, and is, for example, an additional item that can be used in the game executed by the game application program 133, another game related to the game executed by the game application program 133, and the like.

[3. Configuration and Connection Mode of Controller]

Configurations of the left controller 170 a and the right controller 170 b, and a connection mode between the left controller 170 a and the right controller 170 b, and the vehicle 1 and the game machine body 110 will be described with reference to FIG. 5.

The left controller 170 a includes a controller processor 171 a, and a communication unit 172 a, a memory 173 a, a button 174 a, a stick 175 a, an acceleration sensor 176 a, an angular velocity sensor 177 a, a light-emitting diode (LED) 178 a, a vibrator 179 a, and a connector 185 a connected to the controller processor 171 a. The acceleration sensor 176 a and the angular velocity sensor 177 a correspond to an attitude change detection unit of the present disclosure.

The controller processor 171 a controls an overall operation of the left controller 170 a by executing a control program stored in the memory 173 a. The controller processor 171 a performs wireless communication with the game machine body 110 via the communication unit 172 a. In addition, the controller processor 171 a transmits an operation signal of the button 174 a, an operation signal of the stick 175 a, an acceleration detection signal of the acceleration sensor 176 a, and an angular velocity detection signal of the angular velocity sensor 177 a to the game machine body 110.

Further, the controller processor 171 a controls operations (turning on, turning off, and flashing) of the LED 178 a and operations (turning vibration on, turning vibration off, and intensity of vibration) of the vibrator 179 a according to the control signal to the left controller 170 a transmitted from the game machine body 110.

Similarly to the left controller 170 a, the right controller 170 b includes a controller processor 171 b, and a communication unit 172 b, a memory 173 b, a button 174 b, a stick 175 b, an acceleration sensor 176 b, an angular velocity sensor 177 b, an LED 178 b, a vibrator 179 b, and a connector 185 b connected to the controller processor 171 b, and operates similarly to the left controller 170 a. Furthermore, the right controller 170 b includes a camera 180 and transmits an image captured by the camera 180 to the game machine body 110.

The vehicle 1 includes a display 4, speakers 5 a and 5 b, sensors 25, a communication unit 26, and a car navigation system 20, which are connected to the vehicle ECU 10 by a controller area network (CAN) 205. The sensors 25 include a speed sensor that detects the traveling speed of the vehicle 1, an accelerator pedal sensor that detects an operation amount of an accelerator pedal (not illustrated in the drawings) provided in the vehicle 1, a brake pedal sensor that detects an operation amount of a brake pedal (not illustrated in the drawings) provided in the vehicle 1, an illuminance sensor that detects illuminance outside the vehicle, and the like. The communication unit 26 performs wireless communication with a communication terminal such as the smartphone 300 or the like and performs wireless communication with the support server 510 via the communication network 500. The support server 510 is a computer system composed of processors, memories, or the like. The car navigation system 20 includes a global navigation satellite system (GNSS) sensor 21 that detects the current location of the vehicle 1 and map data 22.

The vehicle ECU 10 is connected to the game machine body 110 via a communication line 200, is connected to the left controller 170 a via a communication line 201 a, and is connected to the right controller 170 b via a communication line 201 b. Thus, the vehicle ECU 10 performs wired communication with the game machine body 110, the left controller 170 a, and the right controller 170 b.

The game machine body 110 acquires detection information of the sensors 25, current location information of the vehicle by the GNSS sensor 21, the map data 22, and the like by communication with the vehicle ECU 10, and recognizes the traveling situation of the vehicle 1. In addition, the game machine body 110 can control the display of the display 4 of the vehicle 1 and the sound output from the speakers 5 a and 5 b by communication with the vehicle ECU 10.

In addition, as another configuration, the recognition that the game machine body 110 is held by the game machine body holding unit 60 and the recognition that the left controller 170 a or the right controller 170 b is held by the operation terminal holding units 50, 50 a, and 50 b may be performed on the game machine body 110 side and the left controller 170 a and the right controller 170 b side by a limit switch, a proximity sensor, a magnetic sensor, or the like instead of establishing wired communication with the vehicle ECU 10.

In the case of this configuration, it is not required to connect the game machine body 110, the left controller 170 a, and the right controller 170 b to the vehicle ECU 10, and the game machine body 110, the left controller 170 a, and the right controller 170 b are directly connected by the communication lines 202 a and 202 b, and it is possible to constitute the interaction providing system of the present disclosure just by the game machine body 110. In addition, communication between the game machine body 110 and the left controller 170 a and the right controller 170 b may be performed by wireless communication, and in this case, connection by the communication lines 202 a and 202 b is also unnecessary.

[4. Process of Determining Whether or not to Execute Interaction Control]

A process of determining whether or not to execute interaction control executed by the operation terminal holding recognition unit 121, the terminal device holding recognition unit 122, and the interaction control unit 123 will be described with reference to the flowchart illustrated in FIG. 6. Hereinafter, as described above with reference to FIGS. 1 and 2, processing for a configuration in which the operation terminal holding unit 50 for detachably holding the right controller 170 b is provided in the steering wheel 2 will be described.

In step S1 of FIG. 6, the terminal device holding recognition unit 122 recognizes whether or not the game machine body 110 is held in the game machine body holding unit 60 according to a state of wired communication with the vehicle ECU 10. When wired communication is established between the game machine body 110 and the vehicle ECU 10, the terminal device holding recognition unit 122 determines that the game machine body 110 is held in the game machine body holding unit 60.

In subsequent step S2, when the terminal device holding recognition unit 122 recognizes that the game machine body 110 is held in the game machine body holding unit 60, the interaction control unit 123 advances the processing to step S3. On the other hand, when the terminal device holding recognition unit 122 does not recognize that the game machine body 110 is held in the game machine body holding unit 60, the interaction control unit 123 advances the processing to step S1.

In step S3, the operation terminal holding recognition unit 121 recognizes a state of wired communication between the right controller 170 b and the vehicle ECU through communication with the vehicle ECU 10, and determines whether or not the right controller 170 b is held in the operation terminal holding unit 50. When wired communication is established between the vehicle ECU 10 and the right controller 170 b, the operation terminal holding recognition unit 121 recognizes that the right controller 170 b is held in the operation terminal holding unit 50.

In subsequent step S4, when the operation terminal holding recognition unit 121 recognizes that the right controller 170 b is held in the operation terminal holding unit 50, the interaction control unit 123 advances the processing to step S5 and executes interaction control. On the other hand, when the operation terminal holding recognition unit 121 does not recognize that the right controller 170 b is held in the operation terminal holding unit 50, the interaction control unit 123 advances the processing to step S1. In this case, interaction control is not executed.

[5. Interaction Control]

An execution procedure of interaction control by the interaction control unit 123 will be described with reference to the flowchart illustrated in FIG. 7. Hereinafter, as described above with reference to FIGS. 1 and 2, processing for a configuration in which the operation terminal holding unit 50 for detachably holding the right controller 170 b is provided in the steering wheel 2 will be described.

In step S10 of FIG. 7, the interaction control unit 123 receives detection signals of the acceleration sensor 176 b and the angular velocity sensor 177 b transmitted from the right controller 170 b held in the operation terminal holding unit 50. In subsequent step S11, the interaction control unit 123 recognizes a situation of an attitude change of the right controller 170 b based on the detection signals of the acceleration sensor 176 b and the angular velocity sensor 177 b. The situation of the attitude change includes a change amount, a change direction, a change speed, and the like of the attitude.

In subsequent step S12, the interaction control unit 123 receives the travel information of the vehicle 1 from the vehicle ECU 10. The travel information includes a travel speed, a travel point, a travel route, a destination, and the like of the vehicle 1. In the next step S13, the interaction control unit 123 recognizes the travel state of the vehicle 1 from the travel information.

In the next step S13, the interaction control unit 123 determines information to be output from the output device used in the vehicle 1 based on the situation of the attitude displacement of the right controller 170 b and the travel state of the vehicle 1. The interaction control unit 123 uses the display 141 and the speaker 142 of the game machine body 110, the display 4 and the speakers 5 a and 5 b of the vehicle 1, and the like as output devices.
